Description of the Invention: [Technical Field] The present invention relates to a method and apparatus for position detection, and more particularly to a method and apparatus for capacitive position detection. [Prior Art] Touch Display has been widely used in many electronic devices. The general practice is to use a touch panel (T〇uchSensingPand) to make it difficult to touch display H. Sensing Inf〇rmati〇n is obtained by longitudinally pumping a broom on the touchpad to determine the touch or proximity of external objects (such as the hand and the touch) on the touch boundary, such as the United States. A capacitive touch display provided by US Pat. No. 4,469,720. The sensing information can be converted into a plurality of consecutive signal values by an analog digital converter (Anal〇g_t〇Digital Converter, ADC), and the external value can be judged by comparing the amount of change of the signal values before or after the external object touches or approaches. The location where the object touches or is closest to the touch screen. In general, the controller that controls the touch screen first obtains sensing information when no external object touches or approaches, as a reference value (basdine). For example, in a capacitive touch screen, each of the conductive strips corresponds to a respective reference value. The controller judges whether there is an external object by comparing the subsequent sensing information with the reference value. The 201113794 piece approaches or touches 'and further' to touch the position of the external object. For example, not outside. When the object is close to or touched, the subsequent sensing information is zero or close to the reference value. If the reference value is zero or close to zero, whether the external object is close to or touched. . As shown in FIG. AA, when the external object touches or approaches the sensing device 120 of the touch display 10, the sensor 140 of the sensor 140 is in an axial direction (eg, \axial direction). Converted to a signal value such as the first -B _, corresponding to the shape of the finger, the signal value appears - the waveform or - Finger profile - the peak of the heart 14 is added to the finger touch or Close location. The general two-dimensional sensing information is composed of a plurality of dimensions-sensing information, that is, it is necessary to compile a general rule of _ to be produced, and the - segment is quite long (four). When the _ rate requirement of the touch is high, how to reduce the generation of the two-dimensional sensing information becomes critical. However, the two-dimensional information towel cuts and touches the money, and continuous detection irrelevant to the touch will consume time and power. How to save time and power is an important technical key. It can be seen from the above-mentioned prior art that there are obviously inconveniences and defects, and it is extremely necessary to be advanced. In order to solve the above problems, the relevant manufacturers do not bother to find a way to face the decision, but for a long time - no suitable design has been developed - and the general products and methods have no suitable structure and method 201113794 can solve The above question 'this age: is a problem that the industry is anxious to solve. Therefore, how to create a new technology is one of the most important research and development topics at present, and it has become the goal that the industry needs to improve.

In addition, the sensing information composed of a plurality of consecutive double differences can be regarded as a double differential manufacturing to ualdiffercntial face (4) information). In the present invention, the double difference is not limited to be generated after the signal value or the difference is generated, or the sum or difference of the subtraction of the two pairs of signals may be separately completed when the sensing information is provided, providing similarity or A double differential signal equivalent to the sum or difference of the difference between two pairs of signal values. As described above, the present invention does not limit the form in which the sensed information exists. The double difference can be regarded as another form of the double differential signal of the sensor. In order to simplify the description, the present invention will be described in the following description in the form of a double difference type. The person skilled in the art can infer the implementation of the double differential signal type according to the embodiment of the double difference type. . In one example of the present invention, when an external object touches or approaches the touch device, the two pairs of signal values are composed of three signal values that are adjacent or non-adjacent. In an example of the present invention, the difference between the difference between the first two signal values and the last two signal values is a first difference and a second difference, respectively, and the double difference is the first difference and the first difference The difference between the two differences, wherein the first difference and the second difference are the difference between the previous signal value minus the subsequent signal value or the difference between the subsequent signal value minus the previous signal value. 21 201113794 In another example of the present invention, the difference between the difference between the first two signal values and the value of the last two signals is a first difference and a second difference, respectively, and the difference between the two is - a sum of the difference and the second difference, wherein one of the first difference and the second difference is a difference between the signal values after the other signal values are subtracted, and the first difference and the second difference are One is the difference between the subsequent signal value minus the previous signal value. For example, the two pairs of signal values sequentially include a first signal value, a second signal value, and a third signal value, and the double difference corresponding to the three signal values is (the second signal value _ the first signal value ) + (different signal value third signal value), (second signal value first signal value) _ (second signal value · second signal value), (first signal value - second signal value) + (first The third signal value - the first signal value) or (the first signal value _ the second signal value) _ (the second signal value - the second signal value). When two pairs of signal values are composed of three adjacent signal values, and the external object touches or approaches the touch device, the continuous double difference value of the one-dimensional sensing information may be as shown in the first D picture, wherein the external object The position is the central peak 16 of the sensed information of the corresponding external object, wherein the central peak 16 may fall between the two signal values. When two pairs of signal values are composed of three signal values that are not adjacent, and the external object touches or approaches the touch device, the continuous double difference value of the one-dimensional sensing information may be as shown in the first E-picture, wherein the external The object position is the central peak 17 of the sensing information of the corresponding external object, and its central peak may fall between the two signal values. In the present invention, the sensing information of the corresponding individual sensor, time interval or position may be the signal detected by the sensor. When the signal is analogous, the signal value can be converted into a digital signal by the class 22 201113794 than the digital converter. . Therefore, the difference may be a value of a difference between a pair of signals, for example, a value converted by a pair of signals after being subtracted by a differential amplifier. Similarly, the double difference value may also be a value converted by subtracting (or subtracting) the two pairs of signals by a differential amplifier. One of ordinary skill in the art can deduce that the difference and double difference described in the present invention include, but are not limited to, signal or signal value, and also include recording during hardware or software implementation (electrical recording, magnetic recording). Record, optical record), signal or • Temporary status of the signal value. In other words, the sensing information can be a signal on the sensor or between the sensors, a differential signal (such as a pair of signal differences), a double differential signal (such as the sum or difference of two pairs of signal differences), the signal value, the difference The double difference (signal, difference, double difference after analogy to digital) is another form of existence. Since the signal and signal values, the differential signal and the difference, the double differential signal and the double difference can be presented at different stages of the sensing information. In addition, in order to simplify the description, in the description of the present invention, the touch-related sensing information refers to the sensing information corresponding to the touch or proximity of the external object, such as the original touch-related sensing information, the differential touch-related sensing. Information, double differential touch related sensing information. One of ordinary skill in the art can deduce that in the difference or double difference, the 'zero intersection is located between at least one positive value and at least one negative value, that is, between a pair of positive and negative values (between a pair of Positive and negative values). Corresponding to the difference between the proximity and touch of the external object or the double difference is the intersection of at least the positive value of the 2011 23794 and the at least the negative value, at least the positive value and the at least the negative value are at least mutually separated. -miscellaneous. In most cases, the difference or double difference corresponding to the proximity or touch of an external object is continuous. The multiple positive values are more heterozygous with the negative values. The zero intersection between the positive value and the negative value may be Is at least a zero value or is between two values. The 'signal to earth' touches the opposite signal value to a plurality of consecutive non-zero values, or the reckless energy is a non-adjacent non-zero value _ non-zero value. In some cases, an independent non-zero value that is not adjacent to other non-zero values may be due to noise generated by the need to rely on - or other mechanisms to touch or exclude the coffee. Since it is possible to generate a zero-crossing where the external object is close to the disk touch when the noise is large, in one example of the present invention, the wire falling within a zero value is regarded as a zero value, minus The difference between the proximity of the external object and the touch or the double difference is a continuous multiple of more than one positive threshold and less than one negative gate, and is greater than a value between a positive threshold and a value less than a negative threshold. The meeting place may be at least one zero value or between two values. Combining the above-mentioned 'differential touch-related sensing# information with the double differential touch-related sensing information is an alternating combination of at least a positive value and a minimum-negative value including a zero-crossing intersection, where the zero-crossing of the towel may be at least — Zero value or between positive and negative values. In other words, the present invention compares the differential touch-related sensing information to the continuous differential zero value between the positive and negative values in the double-differential touch-related sensing information, or is regarded as a zero-crossing point, or one of the zero values is zero. At the office. 24 201113794 In the present invention - the example, the touch-off sensing information preset is initiated by at least a positive value or a - 贞 value, and the at least one positive value or the 贞 fiber search includes at least a continuous intersection at the zero intersection. - The ball is at least more heterozygous than the 贞 value, where the parent θ can be at least - zero or between positive and negative values. In the touch-related differential sensing information, at least a positive combination of at least a positive value and at least a negative value is present and at least one positive value and at least a negative value are present in the touch-related double differential sensing information. Alternate combinations appear as no linings. In another example of the invention, the touch detail information is a continuous non-zero value, such as a plurality of consecutive non-zero signal values. The at least one positive value can be regarded as a positive value set, including at least one positive value, and the above-mentioned at least 贞 value can be regarded as a “negative value set” including at least one negative value. Thus, the alternating combination of the upper axes may be a combination of two sets comprising a positive set and a negative set or a combination of three or more sets interspersed with a positive set and a negative set. In the present invention, there may be at least one zero value between zero, one, or a plurality of positive value sets and negative value sets. System Architecture In order to more clearly illustrate the manner in which the sensing information of the present invention is generated, the present invention uses a Shibuya type touch device as an example, and the person skilled in the art can lie 25 201113794 to easily infer other resistance-type, infrared-type, Application of surface acoustic wave and optical touch devices. Referring to the first F-picture, the present invention provides a position detecting device 1A including a sensing device 120' and a driving/detecting unit 13A. The sensing device 12A has a sensing layer. In one example of the present invention, a first sensing layer 120A and a second sensing layer 120B may be included. The first sensing layer 12A and the second sensing layer 120B respectively have a plurality of sensors 14A. The plurality of first-sensors 14GA of the first sensing layer 12A are overlapped with the plurality of second sensors 1 of the second sensing layer 12. In another example of the present invention, a plurality of first sensors 140A and second sensors iA may be disposed in a coplanar sensing layer. The driving/detecting unit 130 generates a sensing tribute according to the signals of the plurality of sensors 14 。. For example, in the self-capacitance detection, the sensed sensor 14A is sensed, and in the mutual point capacitive detection, the sense is not directly driven by the driving/detecting unit 130. The detector 14 〇. In addition, the sensing device 12A can be disposed on the display device 110, and the sensing device 12A and the display device 11 can be configured with a shielding layer (not shown) or no configuration back.

In addition, the controller 160 can include a processor 161 that controls the drive 26 201113794 to generate sensed information, and the sensed information can be stored in the memory 162 for access by the processor (6). In addition, the host (4) constitutes a main body of the computing system, and mainly includes a towel processing unit m, and a storage unit 173 for central processing early access, and a display 110 for displaying the operation result. In another example of the present invention, the controller 160 and the host 170 include a transmission boundary Φ 'control unit to pass through the miscellaneous interface to the host. Those skilled in the art can infer that the transmission interface includes but is not limited to the UART. , USB, 13⁄4, Bluetomh, WiFi and other tree or wireless transmission interface. In one example of the present invention, the transmitted material may be a location (e.g., coordinates), a recognition result (e.g., a gesture code), a command, a message, or other information that can be provided by controller M0. In an example of the present invention, the sensing information may be generated by the processor 161 to generate initial sensing information (such as, for example, 1 sensing information), and the host 170 performs position analysis, such as position analysis, gesture determination, and command identification. and many more. In another example of the present invention, the sensing information may be analyzed by the processor 161 first, and the determined position, gesture, command, and the like are delivered to the host 170.

In the example towel of Figure 2A, the drive unit 13A and _cell are operatively coupled to the sensor 140A via wire W1 and operatively coupled to the sensor 14B via wire W2, respectively. For example, in the self-capacitance detection, the driving unit 13A drives the all-sensors in the -first period via the wire W1, or simultaneously drives the partial sensors 140A. A first axial sensing information (one-dimensional sensing information) is generated by the detecting unit 130B according to the signal of the sensor 140A via the wire W1. Similarly, the driving unit drives or drives all the sensors 14〇B in turn in a second period via the wire W2, or may drive the partial sensors 1 in a divided manner, and the side unit 130B is guided by the wire W2. The signal of the sensor 140B generates a second axial sensing information (one-dimensional sensing information). For example, in the mutual electric valley type detection, the driving unit 130A alternately drives the sensors 14A in the first period via the wire W2, respectively, when each sensor 1 is driven, The unit generates a first-dimensional sensed information corresponding to the first axial direction of the driven sensor via the wire W1 according to the signal touched by the sensor ι, and the first-dimensional one-dimensional sensing information constitutes the first axial one. Two-dimensional sensing information (or an image). Similarly, the driving unit 130A drives the sensors 14 to 8 in turn through the wire W1 in the first dead zone, respectively, when each sensor is driven, the gamma unit is measured by the wire Μ according to the sensor touch 28 201113794 signal A one-dimensional sensing information corresponding to the second axial direction of the driven sensor is generated. The second-dimensional one-dimensional sensing information constitutes a two-dimensional sensing information (or an image) of the second axial direction. In addition, the driving unit 130A and the debt measuring unit 13B can provide synchronization via the line 132 for signal synchronization, and the signal of the line 132 can be provided by the processor 160. Referring to FIG. 2B, the sensing device 12A may also generate a single axial two-dimensional sensing information 'in this example, the wire W2 is driven to drive the sensor 140B' in each sensing. When the device 14〇b is driven, the detecting unit 130B generates a one-dimensional sensing information corresponding to the driven sensor according to the signal of the sensor hoa via the wire W1, and the one-dimensional sensing information constitutes a two-dimensional sensing. Information (or an image). In other words, the position detecting device 10 of the present invention may have the capability of generating two axial one-dimensional sensing information or two axial two-dimensional sensing information, or both having two axial directions. Dimensional sensing information and the ability to sense information in two dimensions can also produce only uniaxial two-dimensional sensing information. The present invention includes, but is not limited to, the above-described capacitive position detecting device, and those skilled in the art can easily infer other applications applied to resistive, infrared, surface acoustic wave, and optical touch devices. Referring to FIG. 3A, the detecting unit 13B is operatively coupled to the sensing device via a wire (eg, W1), and the operative coupling may be achieved by a switching circuit 310. The switching circuit may be a Or a combination of multiple multiplexers, switches 29 201113794, etc., one of ordinary skill in the art can infer the application of other switching circuits. The signal of the sensor 14 can be detected by a detecting circuit 32. When the signal output by the detecting circuit 320 is analogy, the sensing information sensing information SI can be generated through the analog-to-digital circuit 320. Is an analogy or a digital bit' In a preferred embodiment of the invention, the sensing information is in the form of a digit. The present invention includes, but is not limited to, the above examples, and one of ordinary skill in the art will appreciate that the detection circuit 320 and the analog-to-digital circuit 33 can be integrated into one or more circuits. The detecting circuit 320 may be composed of one or more detectors, each of which receives at least one signal of the sensor 140 to generate an output, and the detector may be as shown in the third B to the third D The detectors are shown at 34〇, 35〇, and 36〇. In an example of the present invention, the detection of the signal of the sensor 14〇 may be detected by an integrator, and those skilled in the art may infer that other such as the analog-to-digital device can measure the power. Circuitry of sexual characteristics (such as voltage, current, capacitance, package inductance, etc.) can also be applied to the present invention. The integral ϋ may be implemented in an amplified state Cint having an input (as in the integrator 322 of the figure) or a pair of inputs (as shown by the integrator 324 of the third c and third D figures), The X and output 'output signals can be the value of the SI generated by the analog-to-digital circuit 32'. The generation of each value can be controlled by the - reset signal, such as the third to third D The reset signal is as follows. In another example of the present invention, the signal of the sensor 140 is an alternating current signal, and 30 201113794 is changed with a pair of half cycles. Therefore, the detection of the signal of the sensor 14〇 is also changed according to different half cycles. For example, in the first half of the cycle, the signal of the sensor 14 is detected. In the second half of the cycle, the reverse signal of the sensor 14 is detected, and vice versa. Therefore, the detection of the signal of the sensor 140 can be controlled by a synchronization signal Ssync. As shown in the third B to the third c, the signals of the synchronization signal Ssyne and the sensor 14 can be synchronized or have The same cycle. For example, the synchronization signal Ssync is used to control one or more switches (such as switch circuit milk, milk, milk) to switch between the base points pi and P2' to detect the signal of the sensor 14〇 in the first half cycle, and to detect the sensing in the second half cycle. The reverse signal of the device 140. In the third B diagram, the reverse signal can be provided by an inverter Cinv. In still another example of the present invention, the detection of the signal of the sensor 14〇 is detected by at least one predetermined period (or phase) of at least one period, and may be at least one period and the second period of the first half period. The detection may be performed for at least one period of time, or may be detected only for at least one period of the half period or only the second half period. In the preferred embodiment of the present invention, the first scan-peripheral signal is preferably at least a period of time, and the towel_time is less interfered by the message. The scanning of the detection period may be based on the signal of at least one sensor in the side of each of the at least one cycle. After the touch period is reached, the signal of the sensor 14G is only controlled during the detection period _, and may be controlled by a signal, such as the enable signal in the third to third D pictures. The present invention produces a value of the sensing information 31 201113794 si based on at least the sensing H 14G Wei number. In an example of the present invention, the sensing information si is composed of a plurality of signal values. For example, the image shown in Figure 3B is operatively coupled to the -sensing 140' to detect a signal, and the analog-to-digital circuit 330 is used to generate a threshold value of the sensed SI. In another aspect of the invention, the sensing information si is composed of a plurality of differences. For example, as shown in FIG. 3C, a pair of inputs 312, 313 are operatively coupled to a pair of sensors 14A to detect a differential signal, and then the analog information circuit 330 is used to generate the sensing information si. A difference (or single difference). In still another example of the present invention, the sensing information is composed of a plurality of double differences. For example, the third D picture is shown. The three inputs 314, 315, 316 are operatively coupled to the three sensors 14A to detect a pair of differential signals, and the analog-to-digital circuit 330 generates a pair of differences of the sensing information SI. The double differential signal is generated by the health-to-difference test, and each of the silk signals is generated based on the signal of the sense. In other words, the double differential signal can be generated according to the signals of a first pair of sensors and a second pair of sensors, and the first pair of sensors is the first two of the two sensors. And the second pair of sensors is the last two of the two sensors' three of which may be adjacent or not adjacent. In a preferred embodiment of the present invention, the detection circuit 320 includes a plurality of detectors that simultaneously generate values of all or part of the sensing information SI. For example, the third detection circuit 32 can be composed of a plurality of detectors 340, 350 or 360, and the output of these detectors is converted by the analog-to-digital digit 32 201113794 circuit 330.

The device 324, a device, and the measuring circuit measure the first and second difference signals at one or a plurality of time points to generate the sensing information. For example, as shown in the third map or the J-th graph, the second-order difference signals are measured at a plurality of points or as the second-level difference signals. In the third D diagram, the third I diagram and the third J diagram of the present invention, the signal subtraction and measurement are simultaneously performed by the differential integrator 324, wherein the signal measurement can further include generating a digit by the analog conversion circuit ADC. value. The foregoing related illustrations and descriptions are only one of the examples of the present invention, and are not intended to limit the present invention. Those skilled in the art can deduce that signal subtraction and signal measurement can be performed by different circuits, for example, by a subtraction method. The device passes through an integrator and will not be described here. In the foregoing dual differential circuit, each value of the sensing information is generated by one of the second level difference signals, and each of the second level difference signals is respectively determined by the pair of first level difference values. A first difference signal of the signal is generated by a second 35 201113794 difference signal, wherein the first difference signal is generated according to signals of a first sensor and a second sensor of the sensors respectively. And the second difference signal is generated according to the signals of the second sensor and the third sensor of the sensors respectively. In other words, each value of the sensed information corresponds to the signal of three of the sensors. In a second example of the present invention, the sensing information may be obtained by a differential power path. The differential circuit includes: one or a plurality of subtractors and a measuring circuit, for example, a second C picture, a third G Figure or the third diagram. In these subtractors, the master one subtractor generates a difference signal based on the signals of a pair of sensors, respectively. The measurement circuit measures the difference signals to generate a differential sensing information, wherein each value of the sensing information is a difference between a pair of values of the differential sensing information. In addition, the measurement circuit measures the second level of the difference signal at one or more points to generate the sensing information. For example, the third C picture or the third H picture shows that the second level difference signals are measured at a plurality of time points, or as shown in the third G picture, the second level difference signals are measured at a time point. . In the second C diagram, the third G diagram, or the third H diagram, portions of the subtractor and measurement circuitry may be implemented by integrator 324. The foregoing related illustrations and descriptions are only one of the examples of the present invention, and are not intended to limit the present invention. Those skilled in the art may infer that signal subtraction and signal measurement may be performed by different circuits, for example, by a subtraction method. The device passes through an integrator and is no longer referred to herein by 36 201113794. In addition, each value of the sensing information is a difference between a first difference and a second difference of the differential sensing information, wherein the first difference is a first sensor according to the sensors respectively. The signal is generated by a second sensor, and the second difference is generated according to the signals of the second sensor and the third sensor of the sensors. In other words, each value of the sensed information corresponds to the signal of three of the sensors. In the third example of the present invention, the sensing information may be taken by a measuring circuit as shown in the second B, third E or third F. The measuring circuit measures the signals of the sensors at one or more time points to generate an initial sensing information, and the sensing information is generated according to the initial sensing information, wherein each value of the sensing information is a sense of initiality Three values of the measured information are generated. In addition, the measurement circuit measures the second level of the difference signal at one or more points to generate the sensing information. For example, as shown in the third B diagram or the third F diagram, the second level difference signals are measured at a plurality of time points or, as shown in the third E diagram, the second level difference signals are measured at a time point. . Each value of the sensing information is a difference or sum of a first difference value and a second difference value, wherein the first difference value is a difference between the first two values of the three values of the initial sensing information, and The difference is the difference between the last two values of the three values of the initial sensing information. In other words, the three values of the initial sensing information are a 37 201113794 value, a second value and a third value, and each value of the sensing information is (second value - first value) _ (third value - second value), (first value_second value)_(second value_third value), (second value - first value) + (second value_first value) or (first value, second value) + (second value - brother two value). Each value of the initial sensed information is generated based on the signal of one of the sensors, in other words, each value of the sensed information corresponds to a signal of three of the sensors. In an example of the invention, each touch-sensing information in the sensed information has two zero-crossings' and the position at which the external object approaches or touches is determined based on each of the touch-related sensing information. In another example of the invention, the 'contact thief test information is located at the front or rearmost portion of the information, and the external object only partially approaches or touches the active area edge of the sensing device, and does not have two zero intersections. Where exceptions are required. Furthermore, the aforementioned points in time may include, but are not limited to, portions that pass through one or more clocks, or one or more clocks. Furthermore, the acquisition and generation of the above-mentioned system may be performed by the controller 160; the double differential circuit, the differential circuit and the measurement circuit may be implemented by the controller 160. In the present invention, the sensor may be formed by a plurality of conductive sheets and connecting wires, e.g., a plurality of connecting wires connected in series, or a series of rhombic or square conductive sheets. Structurally, the conductive sheet of the first sensor and the second sensor 38 2〇Π 13794 _ may be different planes of the lake, or may be arranged in the same plane, for example, the first and first sensing layers 12〇α. 120 Β is separated by an insulating layer or a piezoresistive layer, wherein the piezoresistive layer may be composed of an anisotropic conductive paste. For another example, the conductive strips of the first sensor 14A and the second sensor 104B are substantially in the same plane, and the connecting wires of the first sensor Μ() are crossed across the second sensor. 140 连接 connecting wire. In addition, a pad may be disposed between the connecting wires of the first sensor 14 and the connecting wires of the second sensor 14β, and the spacer may be made of an insulating material or a piezoresistive material. Therefore, in an example of the present invention, each sensor senses a sensing range and is sensed by a plurality of sensors including a plurality of first sensors and a plurality of a second sensor, the sensing ranges between the first sensors are parallel, and the sensing ranges between the second sensors are parallel, and the parallel sensing ranges of the first and second sensors overlap to form a An array of overlapping regions. For example, the first and second senses are two rows of infrared receivers arranged horizontally and vertically, respectively, to sense parallel and horizontal parallel scan ranges, and the straight and horizontal parallel scan ranges are interlaced to form a cross. Array of stacked areas. For another example, the parallel and horizontal parallel scan ranges described above are implemented by capacitive or resistive multiple overlapping sensors.

In the first-to-conversion mode provided by the present invention, successive signal values are converted into successive differences, each of which is a difference of - adjacent or non-adjacent signal values. In the second conversion mode of the present invention, the continuous signal value is converted into a continuous double difference, and each double difference is the difference and or difference between the two pairs of signal values. In the third conversion mode provided by the present invention, the continuous difference is converted into a continuous signal 'turn-turn' value plus all the previous or subsequent differences to generate corresponding signal values to form a continuous signal. value. In the fourth conversion mode provided by the present invention, the continuous difference is changed into a double difference of "," and only one difference is a sum of adjacent or non-adjacent pairs of difference values. Or poor. In the fifth conversion mode provided by the present invention, the continuous double difference value is converted into a continuous difference value, and each double difference value is added to each of the preceding or following double difference values to generate a corresponding difference value. Form a continuous difference. In the sixth conversion mode provided by the present invention, continuous double difference values are converted into continuous signal values. In an example of the present invention, each double difference plus all previous double differences is used to generate a corresponding difference, which constitutes a continuous difference of 201113794, and then subtracts all subsequent differences from each difference. The value is used to generate the corresponding signal value to form a continuous signal value. In another example of the present invention, each double difference value is subtracted from each double difference value to generate a corresponding difference value, and a continuous difference value is formed, and then each difference is added to all subsequent differences. The value is used to generate the corresponding signal value to form a continuous signal value. All the difference or double difference added before or after the foregoing may be sequentially generated to generate a corresponding signal value or difference in a shovel or backward accumulation or subtraction manner. The above-mentioned conversion methods include, but are not limited to, one-dimensional sensing information conversion, and those skilled in the art can deduce that the above-mentioned conversion method can also be applied to the two-dimensional sensing information or the sensing information of three-dimensional or more. Moreover, one of ordinary skill in the art can deduce that the above-described operation of the conversion mode can be performed by the aforementioned controller 160 or the host computer. According to this invention, in the present invention, the first form of information (such as one-dimensional, two-dimensional sensing information) is converted into a sensing message for position analysis. In another example of the present invention, the extracted first form of sensing information is converted into a second form of sensing information, and the second form of sensing information is converted into a feeling for position analysis. For example, the continuous double difference value is converted into a continuous signal value ^ -£^^/f(〇ne Dimension Position Analysis) 201113794 The invention provides the first-age analysis based on the plurality of differences in the service Analyze the position of the A zero crossing (lion crossing) as the corresponding position of the external object. The technical personnel of the present technology can infer that the position analysis can include, but is not limited to, the judgment of the proximity and touch of the external object, that is, the judgment of the corresponding position of the external object includes, but is not limited to, the judgment of the proximity and touch of the external object. In an example of the present invention, a pair of adjacent differences including a positive value and a negative value are searched, that is, the positive and negative values on both sides of the zero parent meeting, and then the difference between the adjacent pairs is determined. The position of the parent club, for example, based on the difference between the neighbors and the difference between the two. In addition, it may be based on the order of occurrence of positive and negative values to match the judgment of the zero crossing between adjacent differences. The aforementioned neighboring values may be the difference of the revolutions, or may be intermediate ❿ containing non-adjacent differences of at least - zero values. In addition, it is possible to scale the near positive and negative values in a predetermined order, for example, to search for a pair of adjacent positive and negative values where a positive value occurs first and then a negative value occurs. In another example of the present invention, a threshold value is used to determine a starting position at a zero parent day, and a starting point is used to search for a difference between a positive value and a negative value, and then according to the pair The proximity difference determines the location of the zero crossing. One of ordinary skill in the art can deduce that in the sensing beacon of the difference indication, the sensing information corresponding to the proximity or touch of the external object is greater than a positive door 42 201113794 槛 limit value or less than a negative threshold value. The search performed by this threshold value includes, but is not limited to, the judgment of the proximity or touch of an external object. In other words, in the scan sensory _ _ _ _ whenever the system is greater than - the service limit or less than - the negative door authority value, it can be judged that the domain measurement information exists correspondingly - the zero intersection of the external object approaching or touching. For example, a threshold value corresponding to a positive value is generated by a threshold value, for example, a difference value smaller than a threshold value (such as a positive threshold value) is represented by a pseudo value or a false value (false), and is greater than a threshold value. The difference is represented by 1 or the true value (tme), with the first difference of 10 or the true value of the false value as the starting position, and the zero parent will search for the backward direction. Similarly, the difference may be represented by a 〇 or a pseudo value (false) with a difference greater than a threshold (eg, a negative threshold), and a difference of less than a threshold value represented by 1 or a true value (true), The neighboring difference is one point of (1) or the true value of the true value and the pseudo value is the starting position, and the searching direction of the zero crossing is the forward search. For example, Tables 1 and 4A are examples of determining the proximity or touch of an external object by the threshold value.

Similarly, in the judgment result using the negative threshold value, the starting position is the fifth difference and the twelfth difference of i at the mechanical difference value Q1, and the horizontal bar is taken as an example in the figure. Generation" Two external objects approach or touch. The number of positions of a person of ordinary skill in the art corresponds to the number of external objects approaching or touching, \: 2 external objects limited to peach money are close to the fine touch to 疋 1 or more. In another example of the present invention, a first threshold value and a first threshold value are used to determine a section for searching for a zero intersection, including but not limited to determining the proximity of an external object. Or touch, and then search for the location of the zero intersection in the interval. For example, a binarization value corresponding to a positive value is generated with a first threshold value, for example, a difference smaller than the threshold value is represented by 0 (or a false value), and is greater than a threshold difference. The value is represented by 1 (or true value (plus 〇), starting with 1 where the two adjacent differences are 10. In addition, the binarization value corresponding to the negative value is generated with the second threshold value. For example, the difference greater than the threshold value is represented by 〇 (or pseudo value) and the difference of less than the threshold value is represented by (or true value), and the adjacent two difference is 01 at the end position. In addition, the starting position and the ending position are paired to determine the interval at which the zero crossing is searched. In an example of the present invention, the starting position (such as 1 position in 10) and the ending position (such as in the first place) The slope between the 1 position) determines the zero crossing. One of ordinary skill in the art can deduce that the starting position and the ending position can be interchanged with the ending position and the starting position, respectively. Those skilled in the art can also infer that It is a point where the starting position is 01 and the ending position is 10 to determine the touch phase. For example, taking the fourth picture A and Table 1 as an example, the interval between the first search zero intersection after the pairing is between the fourth and fifth differences, and the second search after the pair is zero. The interval is between the 10th and the 12th difference. One of ordinary skill in the art can deduce that the scan of the positive threshold value 45 201113794 and the negative fm limit of the broom can be simultaneous (or parallel processing), The pairing of the interval may also be the ending position judged after the initial position is judged, and in the example of the present invention, the threshold value is generated according to the sensing information, for example, the threshold value is The maximum of all the difference (four) absolute values is multiplied by a ratio (such as a ratio less than - such as 〇.9), or the positive threshold is Φ, which is determined by multiplying the largest difference by the positive difference. The limit value is determined by multiplying the smallest of the negative differences by the ratio. In other words, the threshold value can be fixed or secret. Therefore, when the absolute record of the service is large, it may happen accordingly. The proximity or touch of the external object is utilized positively The scan of the threshold value is based on 1±{, but the scan towel at the limit of Xiangyumen is not judged. The reverse is also true. The larger threshold is better for filtering noise or ghost points. The smaller threshold value is more conducive to avoiding the actual touch, or it is helpful to judge the proximity of the external object. From the above, it can be inferred that the proximity or touch of the same external object is not _疋The back position is determined by the positive threshold value, or the back position is searched by the negative gate pinch limit value, and the same zero position is searched. In an example, the upper 1 槛 limit and the negative gate plunging limit are used to scan the starting position, and the starting position is searched for the zero 曰曰转搜寻搜寻搜寻触触触触触触触触触触触触触触触The number s 'into the step-received zero-crossing will be disposed of. When subtracted from outside 46 201113794 4 A pair of positive and negative values on both sides of the zero crossing where the object touches or approaches is positive and negative, and the starting position determined according to the positive threshold is backward search for zero crossing. The starting position judged by the negative threshold is the forward search for the zero parent, and vice versa. In addition, the proximity or touch corresponding to the same external object does not necessarily determine the starting position when scanning with the positive door threshold and the negative threshold. A second position analysis provided by the present invention analyzes the centroid position (center of gravity position or weighted average position) as a corresponding position of an external object based on a plurality of signal values or double differences in the sensing information. In an example of the present invention, a threshold value or a double difference value for determining the position of the center of the heart is determined using a threshold value. As shown in the fourth to fourth figures, the binarization value corresponding to the signal value or the double difference value may be generated as a threshold value, for example, the secret service limit value/depreciation value difference value is G-heterogeneous (false A signal or double difference representing 'and greater than the gate limit is represented by 1 or true (true). In this example, the signal value or the double difference represented by 1 or the true value is the signal value or double difference for the 1 chipping position. One of ordinary skill in the art can deduce that the Wei or the double difference financial formula of the limit of the mosquito-like touch is mixed, for example, the 峨 value or the double difference represented by 1 or the true value plus the two sides. The plurality of signal values or double differences of the neighbors are signal values or double differences for determining the position of the centroid. For example, the signal value represented by the phase_continuous or true value or the signal value or the double difference of the phase difference in the double difference is used to take the i and j signal values or the double difference respectively for the forward and backward 47 201113794. The signal value or double difference for judging the position of the centroid. In another example of the present invention, a continuous signal value or a double difference value is converted into a continuous difference value to analyze a corresponding signal value or a double difference value at a zero-crossing point as a central signal value or a double difference value, and then Taking the central signal value or the double difference forward and backward respectively, i and j signal values or double differences are taken as the signal value or double difference for judging the centroid position. In another example of the present invention, the zero crossing is analyzed by the continuous difference and the continuous difference is converted into a continuous signal value or a double difference, and then the corresponding signal value or double difference at the zero crossing is analyzed. The value is used as the central signal value or double difference, and then the center signal value or the double difference value is taken forward and backward to take i and j signal values or double difference respectively as the signal value or double difference for judging the centroid position. value. Suppose that i and j signals are taken forward and backward with the nth signal value. The value is used as the centroid calculation range, and the centroid is judged according to each signal value G in the centroid calculation range and the position A of each signal value. Position (:_^, as follows. t^kck C — _ ^ centroid a n^jk~n-i where x* can be a dimension coordinate (such as X coordinate or Y coordinate) or a two-dimensional coordinate (such as ( Χ,Υ)). 48 201113794 Suppose the difference between the ki signal value and the kth signal value is 仏, and a kth double difference is ==H=(q_Ch)-(ca+1-Ca ) = 2Q—q , assuming that the nth double difference is called forward and backward, and the Jiansi is used as the centroid calculation range. According to the centroid calculation range, each double difference is called the judgment centroid position. DDcentroid, under.

For example, the basic value may be The average value of all the test or double-recorded positions, the value of the signal used to lie at the centroid position, or the average of the multiple or double differences on both sides of the difference, 判断; the signal value or double difference of the position of the centroid A plurality of adjacent non-uses on both sides; a signal value of the j-cut quality u or an average value of the double difference, and those skilled in the art can infer the determination manner of other basic values.

The method can be applied to determine the signal value, difference value, or double difference value of the centroid position, and vice versa. It can be inferred from the above-mentioned saying that the present invention performs positional processing by analyzing the sensing information, including but not limited to the initially obtained signal value, difference value or double difference value.

Similarly, a one-dimensional position analysis is performed on a plurality of second-dimensional (or second-dimensional) multiple-dimension_information's, according to at least a dimensional position corresponding to each external object in the second axial direction, A second one-dimensional centroid position of the outer object in the second axial direction. A two-dimensional position of the parent external object is precipitated by pairing each of the office objects at a first-dimension: position and a second-dimensional quality in the second axis. - In other words, the 'two-dimensional position analysis can be performed by the two-dimensional-up-dimensional sensing information (such as the two-dimensional sensing information on the second axis in the first axis) - the dimensional position Analyze to analyze the two-dimensional position of an external object. 54 201113794 In addition, in a third example of the present invention, the two-dimensional position analysis may be a plurality of one-dimensional sensing information analysis in the axial direction corresponding to a one-dimensional centroid position of each external object, and according to each dimension Sensing the corresponding two-dimensional position of the information, lying in the first-axis direction minus the two-dimensional position of the centroid position of each dimension of each oblique object. The two-dimensional position analysis additionally analyzes the dimensionality of the external objects in a second axial direction corresponding to the dimensional quality of each external object, and judges the first-axis in accordance with the two-dimensional position of each of the information. Corresponding to the two-dimensional placement of each one-dimensional centroid position of each external object. Secondly, the position analysis analyzes the two-dimensional centroid position according to the two-dimensional position of each corresponding dimension-centre centroid position in each of the first and second axial directions. A person skilled in the art can also infer that the two-dimensional sensing information can determine the position of each external object through the image processing program, for example, the water separation algorithm or other county processing can be used for position analysis. For example, the watershed algorithm can be used to analyze the position of each water-dividing collar and then calculate the centroid position by sensing information adjacent to each water-collecting position to obtain a more accurate position. In the fourth example of the present invention, the initially obtained plurality of one-dimensional sensing information is formed by the value of the difference value, and the image (or array) represented by the two-dimensional information is used to calculate the watershed. Method or other image processing for position analysis. It is also possible to use the algorithm of the connected component to analyze the connected parts of the image to determine the image of the external object of the parent, and to analyze the shirt or the external object, such as Hand, palm or pen. In the fifth example of the Japanese invention, the initially obtained plurality of one-dimensional sensing information is represented by a difference value, and then converted into a threshold value or a double difference value to constitute an image (or array) presented by the dimensional sensing information. ), you can use the watershed ^ algorithm or other image processing for position analysis. In the sixth example of the present invention, the initially obtained plurality of one-dimensional sensing negative signals are represented by the difference ', and the position analysis of each one-dimensional sense (four) information is used to determine the intersection of each zero intersection. The position, and the signal value or double difference at the position of each zero intersection, to form an image (or array) presented by a two-dimensional sensing information may be positiond by a watershed algorithm or other image processing analysis. • The double difference at the zero-crossing can be generated by two directly adjacent differences. For example, the zero-crossing is located between _k-Ι difference and the k-th difference, and the double difference at the zero-crossing can be It is £) 仏. The signal value at the zero-crossing can be generated by converting the difference representing the entire one-dimensional sensed information into a signal value, or it can be generated by a plurality of differences closest to the zero-crossing. For example, the nearest n-th signal value of the zero-crossing point takes the average of the i-th signal value and the j-th signal value/~ as the basis of the n-th signal value forward and backward respectively as the basis 56 201113794 basis (^)^ The value ( c_y)=S^ ), with e" ~e_y) as the signal value, then c„-c一=ffl-(M) + ^-(,-2) +-+£)„)- (£ )n+| + ^ + _ + ^ ) 〇2 "~~- For Lu, the difference between the n-th (il) difference and the n+j can be used to determine the zero-crossing Signal value. • In the seventh example of Lin invention, the initial multi-dimensional sensing information is obtained from the information of the miscellaneous money, and then transferred to the county for recording, and the position analysis of each of the sensed information is judged. The position of each zero-crossing point, together with the signal value or the double-key\constituting-two-dimensional sensing information at the position of each zero-crossing, can be a watershed algorithm or other image Process for location analysis. In the eighth example of the present invention, the second-dimensional sense-sensing information is also obtained when the two-dimensional ❹! information_ in the first axial direction or the process towel ′ is obtained. After performing the positional analysis of the two-dimensional intensity on the first axial direction, the -dimensional position or the two-dimensional position of each external object in the first axial direction can be obtained. After the position analysis of the measurement information, the dimension position of each external object in the second axial direction can be obtained. The one-dimensional position in the second axial direction may be paired with the first-dimensional-dimensional position to become a two-dimensional health', or may be replaced or corrected on the second axial direction of the two-dimensional 57 201113794 degree position on the first position. One of ordinary skill in the art will appreciate that the above described two-dimensional position analysis operation may be performed by the aforementioned controller 160 or host 170. Moreover, in one example of the present invention, a one-dimensional distance corresponding to a one-dimensional centroid position of the same external object approaching or touching and at least one other one-dimensional centroid position corresponding to the proximity or touch of the same outer object or The two-dimensional distance is within a threshold. In another example of the present invention, the weighted value of each dimension centroid position corresponding to the proximity or touch of the same external object is greater than a threshold value. In the following description, a touch-related sensing information may be one touch-related sensing information or a plurality of touch-related sensing information in a sensing information, and related operations for a touch-related sensing information. Including, but not limited to, application to a particular touch-related sensing information may also be applied to all touch-related sensing information that may be applicable to the present invention. In addition, for convenience of explanation, many of the illustrations or descriptions of the present invention are mainly described in terms of positive values, and those skilled in the art can deduce that the same viewpoint can also be applied to positive and negative values. Sensing information after values are exchanged. The two-dimensional sensing information proposed by the present invention may be a portion of sensing information having a value of inner low and high outer height as shown in basins 510 of Figs. 5A and 5B. In an example of the present invention, the two-dimensional sensing information including a plurality of double differences is higher in the corresponding touch-related sensing information than in the surrounding when a large range of external objects is touched ( The larger part of the part, the part near the center of 2011 201179 will exhibit a lower depression (smaller value). In another example of the present invention, 'a two-dimensional sensing information that converts all negative values of the two-dimensional sensing information including a plurality of differences into positive values, when the touch range of the external object is greater than the degree of ' In the touch-related sensing information, the portion near the center of the higher (larger value) portion of the touch exhibits a lower depression (smaller value). From the point of view of topographic relief, part of the sensing information with low internal and external high values is the relevant part of the two-dimensional sensing information that constitutes the vaiiey or basin, including the surrounding valley or basin. High and low. For example, 'the valley that can be one or more mountain ranges' such as the basin s_unded by mountains or the canyon (cany〇n), or the top end may have a concave mountain or a terrace. The sense of shouting the value of the outside height may be a canyon with one or more gaps such as gaps at both ends. In the two-dimensional sensing information including a plurality of double-difference φ values, the touch-related sensing information also includes a groove around the valley or the valley. Some of the sensing information relative to the value of the inner low and the outer high is a partial field with a high internal and low value, such as H (such as the hills 521) or multiple peaks (such as the double peak) Hill 522), each part of the sensing information with a value of low inside and outside, the peak is relative to the low (lower value) of the surrounding (smaller value) 'as in Figure 5A and The five hills are shown in 52. In the present invention, the hills with multiple peaks of the example t ′ are part of the sensing information of a plurality of adjacent values of low internal height 59 201113794. For example, in the two-dimensional sensing information including a plurality of signal values, the touch-sensitive sensing information is a part of the sensing information having a value of high inside and outside, and is a hill (smaller range) or a platform (larger range). . Similarly, two-dimensional sensing information including a plurality of double differences or two-dimensional sensing information that converts negative values of all differences into positive values may also include hills and terraces. In an example of the present invention, the portion of the sensing information having the value of the inner low and the outer high is the sensing information related to the touch, and the portion of the sensing information having the value of the inner high and the low is the touch. In another example of the invention, the platform is considered to be a larger hill and the basin is considered to be a valley with no gaps or fewer gaps. In still another example of the present invention, the touch-related sensing information is not a valley or a basin, or a hill or a hill. In addition, when the two-dimensional sensing information is replaced by all the slabs of the two-dimensional sensing body including the plurality of differences, the two-phase (four) high and low low sensing sensation is regarded as being located in the handle _ _News. In the following description, the part of the basin representing the value of the inner low and the outer high is sensed, and the hill is representative of the detailed information having the value of the inner high and the outer low, in order to facilitate the private description of the present invention 'is not limited In the present invention, a person skilled in the art can infer other aspects of the partial information information having the value of the inner low outer S and the sensing information having the inner low and low outer values. 201113794

As shown in step 621, the first driver provides a ~drive signal to all of the first sensors. Next, as shown in steps 622 and 623, when all the first sensors are simultaneously provided with the driving signal, the signals of the first sensors are extracted to generate a first one-dimensional sensing information, and the detection is performed. The first sensor's signal 乂 produces 帛 - dimensional sensing information. Then, as described in step 624, each of the touch-related sensors is determined according to the first-dimensional sensing information and the second-dimensional sensing information. The signal of all the first sensors or the signals of all the second sensors can determine the one-dimensional sensing information, and the device can be shut down according to the judgment of the information on each side of the sensing information. A touch-related sensor that touches the relevant sensing information on each side. For example, the touch-related sensing information as shown in FIG. B, the first c-picture, the first D-picture, or the first one is determined on a dimension sensor, and the touch-related sensor is determined accordingly. . • In an example of the invention, the touch-related sensor may be a sensor comprising a plurality of zero values corresponding to the touch-related sensing information. For example, when the value of the signal is sensed, it may include one sensor on each side, and when the value of the sensed information is a difference, it may include two sensing thieves on both sides. Or when the value of the sensing information is a double difference, it may include three sensors on each side. In step 630, the mutual capacitance detection range may be a mutual capacitance detection method on the first sensor or the second sensor related to all the touches, and the mutual capacitance detection range 62 201113794 The overlap of the __敎# is taken as the mutual capacitance detection range. For example, the second sensing n overlap (four) points of the first sensor associated with all touches and the touch shed are used as mutual capacitance detection ranges. In addition, in step 640, it may be provided in turn to drive the signal to each of the touch-related first-sensors, and when each of the touch-related first sensing fasts is provided with a driving signal, each side- Touching the signal of the related second sensor or all the signals of the second sensing || to determine the sensing information of at least the mutual capacitance detection range. The sensing information that is not corresponding to the at least one mutual capacitance detection range may be zero value or one in the two-dimensional sensing information described in step 650 with respect to the sensing information corresponding to the at least-mutual capacitance _ range. The default value is used to represent. Accordingly, the present invention does not necessarily need to detect all the signals of the overlap, and can also generate two-dimensional sensing information throughout all the overlaps.

Treasury - Wei Lai Qing gift / or second - Dimensional sensing Lai can be generated as the sixth B riding method, because all the first - sensing H eyes are driven 'can avoid wearing water or conductive impurities Interference. For reasons of reason, the mutual capacitance side is judged by reducing the interference of water-splitting or conductive impurities on the sensing device. In the mutual capacitance type, the sensing device is used or the guiding surface _ dry_fine is also The shrinking 'makes the degree of money ringing _ the lowest. For example, all of Kesaki has a stack of mutual capacitance type lie, _ device on the water collapse scales _ interference 2 and all water collapse and conductive impurities throughout. The first-dimensional sensing information and the second-dimensional sensing information may be self-capacitance detection by separately performing the first-level job and the second-level _ ^, and performing self-capacitance on the first ❹in Ah, the driving signals are simultaneously supplied to the first-sensors, and when the second sensors are self-capacitance-detected, the driving signals are simultaneously supplied to the second dampers. This also has the interference of water collapse or conductive impurities on the device, but it consumes more power than the method shown in Figure B, and it takes a long time because it requires two drives. In short, in the manner shown in the sixth figure, the 'the first sense' and the _ of these second implement rail numbers may be simultaneously performed. Of course, the detection of the signals of the first sensor and the second detectors may also be performed separately, but it takes more time. The foregoing sixth A diagram and sixth B_job may be performed by the controller (10) 65 201113794, and the related details have been disclosed in the above description, and will not be described herein. In addition, in the above description, the driving or/and the sampling of the first sensors can also be inferred to be suitable for driving or/and detecting the two-dimensional sense. In a second embodiment of the present invention, a method of capacitive position valence is shown in Figure 7A. First, as shown in step 71, the two-dimensional sensing information is obtained. Next, as shown in step 72, at least one one-dimensional sensing information is obtained. Then, as shown in step 730, at least one detected range is determined in the two-dimensional sensing information according to the at least one-dimensional sensing information when the capacitive sensing device is touched or approached. Thereafter, as shown in step 74A, each touch-related sensing information is determined in the at least one detected range. The plurality of one-dimensional sensing information may be obtained by a capacitive sensing device, and the capacitive sensing device includes a plurality of sensors, the sensors including a plurality of first sensors and a plurality of second The sensor, wherein the first Lulu sensor and the first sensing benefit parent are in a plurality of overlapping points. Further, the above steps 710 to 720 may be performed by the controller 160. Additionally, the above steps 730 through 740 may be performed by the aforementioned controller 160 or host 170. In an example of the present invention, a two-dimensional sensing information is obtained by mutual capacitance detection, and one-dimensional sensing information is derived according to the two-dimensional sensing information. For example, the second one-dimensional sensing motion is generated according to the sum of all the values of each of the first dimension information, that is, each value of the first one-dimensional sensing information is respectively according to one of the first sensing information. The sum or difference of values is generated. For another example, each value of each of the 2011 20111794 first-dimensional sensing information is generated according to one or two of the sensors, so each value corresponds to the dimension position, and the dimension sensing is performed. Each value of the information is generated based on the sum or difference of all values corresponding to the same one-dimensional position in the two-dimensional sensing information. In other words, it is possible to obtain one-dimensional sensing information corresponding to the first sensors and/or the second sensors only by performing mutual capacitance detection to determine the touch correlation of the one-dimensional sensing information application. Sensing information, or further identifying the sensor that touches the relevant •. In another example of the present invention, the one-dimensional sensing information corresponding to the first sensors and/or the second sensors may be generated by self-capacitance detection. As shown in steps 610 to 630 as described above, all of the first axial sensors are driven by a driving signal, and signals of all the sensors in the first axial direction are detected to generate all sensing corresponding to the first axial direction. One-dimensional sensing information. In addition, it is also possible to detect the signals of all the sensors in the second axial direction when all the sensors in the first axial direction are driven to generate one-dimensional sensing information corresponding to all the sensors in the second axial direction. For another example, one-dimensional sensing information corresponding to all of the sensors in the first axial direction may be generated by self-capacitance detection of all of the first axial sensors. Similarly, the one-dimensional sensing information corresponding to all the sensors in the second axial direction may be generated by self-capacitance detection of all the sensors in the second axial direction. The first axial direction and the second axial direction may be 67 201113794 and the other of the horizontal axis or the vertical axis, respectively, and the sensor in the first axial direction and the sensor in the second axial direction may respectively be the first A sensor and one of the second sensors and the other one determine that at least one of the measured ranges may be as shown in FIG. First, as shown in step 731, it is determined that at least one of the sense sensing information of the one-dimensional sensing information is touched. Next, as shown in step 732, the touch-related range of each touch-related sensing information in the two-dimensional sensing information is determined. Thereafter, as shown in step 733, at least one detected range is determined according to each touch correlation range. In addition, the at least one detected range may be a parent set or difficult for all touch related ranges. In addition, each of the values of at least the - dimensional sensing information corresponds to a range on the two-dimensional sensing information, and each of the touch-related ranges is a corresponding range of all values of the corresponding touch-related sensing information.
